? 1.2.2工作原理 ? 探测器采用红外线散射原理探测火灾产生的烟雾, 探测元件主要由红外发射、接收对管及光学暗室 (也称“迷宫”)组成,光学暗室可屏蔽外界杂 散光干扰但不影响烟雾颗粒进入。 ? CPU控制红外发射管周期发光,在无烟状态下接 收管只接收到很弱的红外光,当有烟雾进入时, 由于散射作用使接收光信号增强,经放大后的电 信号由CPU实时进行A/D转换。当超过设定判据 时,CPU 通过总线向控制器返回报警信号。 ? 前向/后向双光路设计,利用对各种烟雾响应变 化量的比值不同实现对各种烟雾响应的均衡性。
? 1.2.2 Working principle ? The detector adopts infrared scattering principle to detect fire smoke detection device, mainly composed of an infrared transmitting, receiving pipe and optical darkroom ( also known as the" maze" ) composition, optical darkroom can shield external interference of stray light but does not affect the smoke particles into. ? CPU control infrared emission control cycle in luminescence, smoke-free state receives the tube receives only very weak light, when smoke enters the smoke, due to scattering effect to the received optical signal enhancement, the amplified electrical signal by the CPU real-time A/D conversion. When exceeding the set criteria, CPU through the bus to the controller returns the alarm signal.
? 消防注意事项 ? 第一条、现场必须有适当的灭火用具和器材,并放在明显、固 定的地点。First, there must be proper fire fighting tools and equipments at site, and they must be layed on obvious and fixed place. 第二条、现场的消防设备和用具, 不得随意挪做他用。Secondly, the fire fighting tools and equipments at site cannot be abused.第三条、现场失火
时,工作人员应坚守岗位,由值长组织扑救并与消防队联系、汇 报领导;消防车未到,安排专人迎接消防车辆,告之着火地点。
Thirdly, the worker should stay at their posts when there’s fire at site, the chief team leader organize the fire fighting, contact with fire brigade, report to the leader; arrange people to take the fire trucks to the firing place before their arrival.第四条、灭火时,根据不同 情况使用灭火器,保护机组不受损失。Fourthly, use different fire extinguishers according to different conditions when fire fighting, protect the unit.
? 第五条、带电设备或电缆着火时,应先切断电源再进行灭火,
Fifth, cut off the power before fire fighting when electrical
equipment and power cable catch fire.1.电机
着火时,先拉掉电源,使用干粉灭火器灭火,不准用砂子灭火。
1.Cut off the power if the motor catch fire, use powder fire extinguisher for fire fighting ,and sand is not allowed to use .2其他电器着火,先切断电源,用C02灭火器 或干粉灭火。2.Cut off the power if other electrical apparatus catch fire, then use C02 fire extinguisher or powder fire extinguisher for fire fighting. 3油类着火时,
不可用水扑救,应用泡沫灭火器或砂土扑救,但油系统或油箱着 火禁止用沙土。3. Water cannot be usee for fire fighting
when oil firing, use foam fire extinguisher or sand, but sand is not allowed to use when oil system or oil tank catch fire.
